WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 771,750, dated October4, 1904.

Application filed March 3, 1904. Serial No. 196,374:- (No model.)

T0 at whom it may concern.-

Be it known that I, JAMES E. RUBY, a citi- Zen of the United States,residing at Cosby, in the county of Andrew and State of Missouri, haveinvented new and useful Improvements in Washing-Machines, of which thefollowing is a specification.

My invention relates to new and useful improvements in washing-machines;and its object is to provide a device of this character having acombined rotary and reciprocating rubber.

Another object is to provide means whereby the rubber may be adjusted soas to operate upon any number of clothes which may be placed within thetub of the machine.

A further object is to provide novel mechanism for producing areciprocating as well as a rotary movement of the rubber.

With the above and other objects in view the invention consists of a tubupon the top of which is arranged a supporting-frame in which isadjustably mounted a cross-plate. This cross-plate has a cam-shapedflange depending therefrom which forms a bearing for a roller arrangedat one side of a revoluble vertical shaft. This roller is held normallyin contact with the cam by a spring located therebelow. A rubber issecured to the lower end of the shaft, and operating means are connectedto the other end thereof.

The invention also consists in the further novel construction andcombination of parts hereinafter more fully described and claimed, andillustrated in the accompanying drawings, showing the preferred form ofmy invention, in which Figure 1 is a vertical section through themachine. Fig. 2 is a bottom plan view of the rubber. Fig. 3 is a topplan view thereof. Fig. 4; is an enlarged section on line 4: 4, Fig. 1.Fig. 5 is an enlargedelevation of the supporting-frame and the partsconnected thereto, and Fig. 6 is a side elevation thereof.

Referring to the figures by numerals of referenoe, 1 is a tub of anysuitable construction and having a removable cover 2. Secured on thiscover at the center thereof is a supporting frame comprising oppositelydisposed similar standards 3, connected at their upper ends by across-strip A. Each of the standards has a longitudinally-extendinggroove 5 therein, and the edges of the grooves have notches 6, as shown.Revolubly mounted within the cross-strip 1 and within a baseplate 7located therebelow'and upon the cover 2, is a shaft 8, the lower end ofwhich is secured in the center of a circular rubber 9. Pins 10 projectdownward from this rubber adjacent the center thereof, and conicalrecesses 11 are formed at suitable intervals within the lower face ofthe rubber and adjacent its periphery. Each of these recessescommunicates at its upper end with an outlettube 12 of any preferredconstruction and which is preferably held in place by means of a nut 13.An adjusting-plate 14: extends through the slots 5 and has enlargedportions 15, which are adapted to be moved intoengagement with thenotches 6. A slot 16 is formed longitudinally within the plate 14, nearthe center thereof, for the reception of the shaft 8. A cam 17 ispivoted to the plate 14 near one end and is adapted to bear against oneof the standards 3 and lock the' plate against longitudinal movement. Acircular flange 18 extends downward from the plate 1 1 and is concentricwith the shaft 8 when the plate 14 is locked against movement. Thisflange has its lower edge cut away to form cam-plates upon which bears aroller 19,which is mounted upon one side of the shaft 8. A spring 20incloses the shaft 8 and bears at opposite ends upon the base-plate 7and the pin 21, on which roller 19 is journaled. A powerwheel 22 isconnected to the upper end of the shaft 8.

After the clothes to be washed have been placed within the tub l andsaid tub has been filled with water the cover 2 is placed in position,and the rubber 9 will therefore bear upon the clothes contained withinthe tub.

- The plate 14 is then slid longitudinally, so as to bring its enlargedportions 15 into position within the adjoining notches 6, and theseenlarged portions are locked within the notches by the cam 17. Shaft 8is then rotated" by means of the wheel 22, and during this movement theroller 19 travels upward and downward upon the cam-face of flangelS andalternately compresses and relaxes the spring 20. It will thus be seenthat as the shaft 8 and rubber 9 rotate the same will also be movedvertically upward and downward, thereby producing a pumping operationwhich facilitates the cleaning of the clothes operated upon by therubber.

In the foregoing description I have shown the preferred form of myinvention; but I do not limit myself thereto, as I am aware thatmodifications may be made therein without departing from the spirit orsacrificing any of the advantages thereof, and I therefore reserve theright to make such changes as fairly fall within the scope of myinvention.

Having thus described the invention, what is claimed as new is- 1. In awashing-machine, the combination with a tub having a revoluble rubbertherein, and a shaft extending from the rubber; oflongitudinally-slotted standards upon the tub and at opposite sides ofthe shaft, a holdingplate adjustably secured within the standards andinclosing the shaft, a cam depending from the plate and inclosing theshaft, a springpressed roller upon the shaft and bearing upon the cam,and means for rotating the shaft.

2. In a washing-machine, the combination with a rotary rubber, and ashaft extending therefrom; of a tub, longitudinally-slotted standardsupon the tub and at opposite sides of the shaft, said standards havingnotches therein, a holding-plate adjustably mounted within the slots andadapted to engage the notches, means for locking the plate in adjustedposition, a cam depending from the plate and inclosing the shaft, aspring-pressed roller connected to the shaft and bearing on the cam, andmeans for rotating the shaft.

3. In a washing-machine, the combination with a tub having a revolublerubber therein, and a shaft extending from the rubber; oflongitudinally-slotted standards upon the tub and at opposite sides ofthe shaft, said standardshavingnotches,aholding-plate adjustably mountedwithin the slots and adapted to engage the notches, means for lockingthe plate in engagement with the notches, a circular cam extending fromthe plate and inclosing the shaft, a roller journaled upon one side ofthe shaft, a spring inclosing the shaft and adapted to hold the rollernormally in contact with the cam, and means for rotating the shaft.

In testimony whereof I aflix my signature in presence of two witnesses.

JAMES E. RUBY.
